Guides/Use case
Keep a diary on a shared computer — sealed with a password
A shared computer is a house with thin walls. Elba lets you keep a private journal in a sealed folder that other users of the same machine cannot open, even if they poke around.
Why a folder name is not privacy
Anyone with access to the drive can rename ‘Private’ to something else. A sealed folder resists inspection because there is nothing to inspect but encrypted bytes.
A daily routine
Open Elba, unlock the vault, write, save, and re-lock before you walk away. The journal returns to being a box only you can open.
Questions people actually ask
- What if someone deletes the vault?
- Encryption doesn't protect against deletion. Keep a copy on a USB stick or a cloud drive.
- Can they see what I write while I write it?
- Only if they are watching your screen. Elba can't help with shoulders.
Take the island
Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
